CSX features both a Lagless version (with low computer-intensive models/sounds/codes) and a Lockdown expansion pack (for the higher-end computers). The improvements and changes this mod makes on the usual Counter-Strike 1.6 are outlined below:

Visual:

Game-play:

A modified version of Geesu's war3ft mod with 10 races, 25 levels, and 5 trainable skills and 1 ultimate per race. New skills, sounds and sprites are included. War3ft bugs such as night elf evasion are fixed, and mole system improved. Maps can be played either with objectives or without objectives. Maps can also be played with a Match-style feature, which changes the map once a team reaches 10 wins (unless entering over-time). Alternatively, a map voting system occurs per 25 mins, changing the map after the last round ends.

Fun:

Killing spree sounds and sprites, in-game karaoke menu with over 200 songs and lyrics, over 400 *special* wall pictures, in-game menu with over 80 different knives, 5 different monsters with extra health and speed, over 50 new maps with bot navigations, 40 different selectable player models with accompanying descriptions in team select menu

Complete Customisability:

Can't stomach the extra gore? Don't like the realistic loading? Prefer smoke grenades and flashbangs with its original colour? Every part of the game can be customised to your liking, through an in-game menu. Simply press a button and decide which plugins should be enabled or disabled.
